Their dentist referred this patient to us. He was on holiday and developed toothache and then noticed a fluid filler blister on the side of the gum adjacent to the tooth.
Clinically the upper left first molar was tender and there was a fluid filled blister present on the gum.
An X ray revealed a large area of infection depicted by the arrows.
What is also noticeable is that the root filling is short of the tip of the root. This most likely means that this unfilled part of the root has bacteria which has resulted in the infection.
This x ray shows the root filling to length –depicted by the blue arrows - and an additional root was located and filled –red arrow.
12 months later and the bone has healed, the patient is symptom free and the blister on the side of the gum has resolved
